ATTORNEY should he understood that the valves 19 are operated at plopcr times for controlling the admission and exhaust of gases to and from the explosive cylinder.

It should he of course understood that. certain f,obvious detail mechanical changes may be made in the present device Without departing from thepirit of the in\ention,

so long as these changes fall within the scope of the appended claims. i

What is claimed is 1. An engine of the class described comprising a cylinder, a suction piston head carried within said cylinder, an auxiliary piston head working below said suction piston head, said auxiliary piston head provided with a depending neck portion, a piston rod extending through said neck portion and supporting said suction. piston head, ls'ai'd piston rod provided with a plurality of lugs formed upon the sides thereof, said neck portion provided with a plurality ofgrooves formed therein for constituting a track for said lugs, a link connected to thelower end of said piston rod, a crank shaft, said link connected to said crank shaft, and meansconnecting said crank shaft to said auxiliary piston.

2. An engine of the class described comprising a cylinder, a suction piston head carried within said cylinder, an auxiliary piston head working below said suction piston head, said auxiliary piston head provided with a depending neck portion, a piston rod extendmg through said neck portion and .supporting said suction piston head, said link and piston rod as said crank shaft 1s operated.

3. An engine of the class described comprising a cylinder, a plurality of piston 'heads mounted within said cylinder, one of said piston heads provided with a depending neck portion, a piston rod extending through said neck portion and supporting the other piston head, said neck portion and pistonrod provided with guiding means for facilitatmg the reciprocation of said piston rod through said neck portion, a crank shaft,f

means connecting said rod to said crank shaft, and means connecting said neck portion to said crank shaft.

4. An engine of the class described comprising a cylinder, a plurality of pistons working Within said cylinder, one of said pistons provided with a depending neck portion, a piston rod extending through said neck portion and supporting the other piston head, guiding means carried by said piston rod, said neck portion rovided with guiding means coperating Wit said first mentioned guiding means, a crank shaft, a link connected to said crank shaft and engaginfr said piston rod, nd a link engaging said neck portion and \a so engaging said crank shaft.

for facilitating-the operation of said crank shaft as said pistons are operated.
